Work in progress.... Slooooowwly
TO Run MTK-SU and then the backup helper
Script to be used in android termux app
This process uses "curl" and "git" to sync with files on internet, so an active internet connection is needed.
Install termux and run these four commands to make sure you have needed termux resources
pkg update
pkg upgrade
pkg install curl
pkg install git
Then use curl to copy the "mtk-su.sh" script to termux with the following commands The script is same at github location. Just easier to use "del.dog" to shorten the url.
curl https://del.dog/raw/mtk-su.sh > mtk-su.sh
chmod +x mtk-su.sh
./mtk-su.sh
This will download latest version of mtk-su, then check which version (32-bit or 64-bit) that is needed to run on your device. Then it will run the backup-maker script, and give the option to backup boot and recovery or all partitions.
There is no gaurantee that this mtk-su will work on your particular device. If you fail to complete the first method , using mtk-su and backup-helper together then after getting root (some other way) you can still run back-up helper by itself
To run just the Backup-help curl from this address
curl https://raw.githubusercontent.com/mrmazakblu/Root-Backup-Helper/master/dd-backup-maker.sh > maker.sh
chmod +x maker.sh
Next part will need root to work. The method above includes a root step.
./maker.sh
At the end of the maker.sh, you will get 3 options.
